1. Why do children have stronger immune defenses?

The immune system of children is more powerful than that of young people and adults. A study coordinated by the University of Padua and published on JAMA Network Open, reports that the level of antibodies decreases with age and the immune defense lasts less long. From an examination of 252 families (700 people, half children) whose unvaccinated members had become ill with Covid before summer 2021, in a mild asymptomatic form, it emerged that children under the age of 3 had levels of antibodies 5 times higher than in an adult, but also 3 times higher than in a boy between 12 and 18 years old. This difference persisted over time. A child’s antibody levels after 10 months of infection were more than double those of an adult between 1 and 4 months after Covid.

2. Can the influenza A virus protect against Covid?

Who would have thought. The flu is an ally against the severe forms of Covid. Research published in the American Society for Microbiology’s Journal of Virology and conducted by New York University scientists Langone Health found that the influenza A virus could interfere with Covid replication even one week after the elimination of the pathogen, that is, after recovery. “Covid and the influenza A virus can infect the airways, and are related to significant morbidity and mortality rates, so understanding the consequences associated with coinfection is critical,” the researchers stressed. according to experts, they could pave the way for the definition of new strategies aimed at safeguarding public health.

3. Will we get vaccinated against both Covid and the flu in the fall?

The pandemic wave is worrying. Until a few months ago the virus seemed defeated, then the arrival of new variants, in a very short time and increasingly contagious, made it clear that the battle will still be long. Now there is fear for autumn when Covid will overlap the usual one flu epidemic. The situation could become more troubling as more time will be spent indoors where transmission is easier. Last year the precautionary measures such as the Green Pass, the spacing and the obligation of the mask had greatly reduced the influence, almost to cancel it. Now that these restrictions have lifted, it is estimated that the flu virus may return to hit more. What to do to protect yourself? While the fourth dose operation has started, the EMA, the drug agency and the WHO have asked in recent days to “consider the co-administration, where possible” of the two vaccines. In particular, family doctors who have always been involved in the campaign against the seasonal virus will be involved. In autumn, therefore, two vaccines could be made on the same day.
